Weather in September
Temperature
The onset of September marks an average high-temperature of a still fiery hot 36°C (96.8°F), hardly differing from August's 36.2°C (97.2°F). Manono sees a major change from daytime highs, with the nighttime temperature dipping to a pleasant 22.7°C (72.9°F) on average during September.Heat index
The average heat index in September is computed to be a blistering 41°C (105.8°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.One should consider that heat index numbers are for shaded settings and light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
Humidity
The average relative humidity in September is 44%.Rainfall
In Manono, during September, the rain falls for 13.5 days and regularly aggregates up to 33mm (1.3") of precipitation. Throughout the year, there are 215.5 rainfall days, and 1157mm (45.55") of precipitation is accumulated.Daylight

Sunshine
In Manono, the average sunshine in September is 10.2h.UV index
May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for average individuals.Note: In September, the maximum UV index of 7 suggests these recommendations:
Shield from overexposure. Defense against sun-related harm is required. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. Experience reduced UV exposure by about half when donning a wide-brim hat.
